Well - you *do* have some idea of what sort of abuse you're trying to stop, right?

If they're not allowed to call it more than X times/hour, rate limit your RPC
server.  Or apply whatever other checks you want to.

At least you (hopefully) don't have to worry about the user running your
server under a debugging tool to reverse engineer it. :)
